Lady Gaga may have had the happiest birthday ever.
Not only did she perform last night in L.A. for more than 20,000 people on her 25th birthday, but after she sang her heart out for the Staples Center, they serenaded her.
"Her dancers gave her a cake at the end and the entire crowd sang 'Happy Birthday'," a concertgoer tells me, "She started crying!"
And guess what other gift she got, that no one else in the world has yet (no, not another meat suit)?!
Nine million followers on Twitter.
Gaga already bounced Britney Spears from her Twitter reign nine months ago as having the most followers, but yesterday she became the first person to hit the 9 million mark.
Famous faces in the house for Gaga's show last night included Adam Lambert and Diane Keaton. Gay or straight, younger or older, Gaga clearly has mass appeal!
